Ovulation?

Th

Hubby has been gone for a month but finally came home on the 12th, which was supposed to be the day before my ovulation. According to the app my ovulation should have been on the 13th, however my temps are looking like today is ovulation. I am just confused because even though I know my ovulation should be near and my temp dropped significantly this morning, my clear blue digital ovulation test have only shown up negative (empty circle). Does this mean I still ovulated? Should I go based off my BBT or based off ovulation tests? Help!
